Problems solved by technology

However, these solutions are not effective in determining whether a web page has been altered by malware, and identifying unusual elements in a web page version on the user's side without installing additional software
At the same time, add-on software such as various security clients, thin clients (light agents) and other antivirus components cannot always be installed on the client side, which eventually leads to errors in the operation of antivirus applications

Abstract

Disclosed are system and method for detecting anomalous or malicious elements of a web page. One exemplary method comprises: obtaining data about elements of a tested web page; generating at least oneN-dimensional vector characterizing elements of the tested web page; retrieving a statistical model of known malicious web page elements; comparing the at least one N-dimensional vector with clustersof the statistical model of known malicious web page elements, by measuring the distance of the N-dimensional vector of the element and centers of all clusters of the statistical model; and identifying at least one malicious element of the tested web page based on results of the comparison.

Description

technical field [0001] The present invention relates generally to the field of network security, and more particularly to systems and methods for detecting malicious elements of web pages. Background technique [0002] Recently, banks and other financial institutions have proactively adopted online banking services (Internet banking) as part of banking services. Internet banking is a generic term for technologies used for remote banking services and access to accounts and operations (with accounts) that are available at any time and from any computer that has access to the Internet. For these operations, a web client such as a browser is usually used. [0003] The widespread use of such technologies naturally attracts hackers, who are interested in stealing funds from the accounts of users of remote service systems. One of the common attacks on users of online banking is that of placing malware in place of the content of web pages displayed to the user. Malware embeds HTM...
